Abstract
The utility model provides a kind of Hall switch, this Hall switch forms primarily of pedestal, guide rod, magnet, Hall element, spring, indicator light and circuit board, described Hall element does not contact with magnet, because this reducing the probability because being damaged by external force affects frequent operation, extend useful life, and adopting the switch of Hall element and magnet composition, user directly cannot contact the switch of Hall element and magnet composition, also operation error is less likely to occur.
Description
[technical field]
The utility model relates to a kind of switch, particularly relates to a kind of Hall switch.
[background technology]
In the prior art, mechanical pressure switch drives switch jaw contact electric contact drive work by tablet press mechanism, because be easy to after frequent operation damage, causes useful life short and easy faulty operation
Therefore, be necessary to improve existing technology, to solve above technical problem.
[utility model content]
The purpose of this utility model is to provide the Hall switch of a kind of contactless, low-power consumption, long life, response frequency high, because physical switch key is cancelled, user directly cannot contact the switch of Hall element and magnet composition, therefore misoperation is less likely to occur.For achieving the above object, the utility model adopts following technical scheme.
A kind of Hall switch, establish the pedestal of container cavity in comprising and be arranged on the spring of container cavity, Hall element radial direction is arranged in pedestal, it is characterized in that, described container cavity openend is for installing guide rod, the depressed part of described guide rod is for placing magnet, and described magnet can move together along with guide rod, and described Hall element does not contact with magnet.
Described at least one magnetic conduction sheet winding is outside described magnet.
Described magnet is square, and described magnetic conduction sheet winding is in the side of block magnet.
[accompanying drawing explanation]
Fig. 1 is the schematic perspective view of an execution mode of the Hall switch that the utility model provides;
Fig. 2 is the internal structure cross-sectional schematic of the Hall switch execution mode shown in Fig. 1;
[embodiment]
Fig. 1 is a stereogram of the present invention.
Fig. 2 is the schematic diagram of Hall switch structure of the present invention, this Hall switch, comprise the pedestal 1 being provided with container cavity 2, inside be located at the magnet 4 at guide rod 1 recessed position place, spring 5 is arranged in container cavity 2, one end end abuts guide rod 3, and the other end abuts the wall portion that pedestal 1 cavity place is formed, and it is inner that Hall element 6 radial direction is arranged on pedestal 1; Indicator light is arranged on circuit board 9.
Particularly, when promoting guide rod 3, magnet 4 is along with guide rod is toward the motion of spring 5 direction, and when moving to certain stroke, magnetic flux increases, due to Hall effect, and switch conduction, indicator light 7 is bright; When guide rod 3 does not have the masterpiece used time, guide rod resets under spring 5 acts on, and magnet 4 is away from Hall element 6, and switch disconnects, and indicator light 7 extinguishes.
Magnet 4 in above-described embodiment can be square, also can adopt other shape further, can control equally to switch.
In above-described embodiment, can winding magnetic conduction sheet 8 outside magnet 4, adopt the method for winding that the leakage field of the magnet 4 in magnetic conduction sheet 8 is reduced; The magnetic flux quantitative change of magnetic conduction sheet 8 is large, and during rotor magnet 4, the sensitivity of Hall switch is higher, and reaction is rapider, and the waveform of output is also smooth.
In above-described embodiment, eliminate physical switch button, by the change of Hall switch and magnet iron piece induction, realize the disconnection of power circuit with closed.Because physical switch key is cancelled, user directly cannot contact the switch of Hall element and magnet composition, therefore misoperation is less likely to occur.
In above-described embodiment, Hall element does not contact with magnet, avoids magnet and Hall element because be easy to damage after frequent operation.
It should be noted that: the technical scheme of above embodiment only for illustration of the utility model and described by unrestricted the utility model, although this specification has been described in detail the utility model with reference to the above embodiments, but, those of ordinary skill in the art is to be understood that, person of ordinary skill in the field still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, all should be encompassed in right of the present utility model.
Claims (3)
1. a Hall switch, establish the pedestal of container cavity in comprising and be arranged on the spring of container cavity, circuit board, indicator light, Hall element, Hall element radial direction is arranged in pedestal, it is characterized in that, described container cavity openend is for installing guide rod, and the depressed part of described guide rod is for placing magnet and magnetic conduction sheet, described magnet can move together along with guide rod, and described Hall element does not contact with magnet.
